4. Opstelling

4.1 Battery installasie

1. Vind die batteryklepdeksel aan die agterkant van die meter.
2. Use a screwdriver (if necessary) to open the battery compartment.
3. Insert one 9V (IEC 6LR61) battery, observing the correct polarity (+/-).
4. Plaas die deksel van die batterykompartement terug en maak dit vas.

Note: A low battery indicator will appear on the display when the battery needs replacement.

5. Bedryfsinstruksies

5.1 Krag aan/af

• Druk die KRAG knoppie om die meter aan te skakel.
• Druk die KRAG knoppie weer om die meter af te skakel.
• The meter features an automatic power-off function, which will turn off the device if no keys are operated for more than 10 minutes.

5.2 Basiese Meting

1. Skakel die meter aan.
2. Point the light sensor towards the light source to be measured.
3. The illuminance value will be displayed on the LCD. The meter automatically selects the appropriate range.

5.3 Range Switching (Auto/Manual)

The MS6612 supports both automatic and manual range switching.

• In auto-ranging mode, the meter automatically selects the best measurement range.
• Druk die RANGE button to switch between auto and manual ranging modes. In manual mode, you can cycle through available ranges.
• If the measured value exceeds the current range in manual mode, the LCD will display "OL" (Overload).

5.4 Data Vashou Funksie

Om die huidige lesing op die skerm te vries:

• Druk die HOU button. The "HOLD" indicator will appear on the display.
• Druk die HOU button again to release the data hold and resume live measurement.

5.5 Maximum/Minimum Value Measurement

Om view the maximum or minimum illuminance recorded during a measurement session:

• Druk die MAX/MIN button. The display will show the maximum recorded value.
• Druk MAX/MIN again to cycle to the minimum recorded value.
• Druk MAX/MIN a third time to exit this mode and return to live measurement.

5.6 Peak Value Measurement

This function captures the highest instantaneous illuminance value.

• Druk die PUIK button to activate peak measurement. The "PEAK" indicator will appear.
• The display will show the highest illuminance detected since activating the function.
• Druk PUIK weer om hierdie modus te verlaat.

5.7 Relative Value Measurement

This function allows you to set a reference point and measure the difference from that point.

• In a stable light environment, press the REL button. The current reading becomes the reference, and the display will show "0".
• Subsequent measurements will show the difference (positive or negative) from this reference value.
• Druk REL again to exit relative measurement mode.

5.8 Zero Calibration Function

To ensure accuracy, especially in low light conditions, perform a zero calibration.

• Place the light sensor in a completely dark environment (e.g., cover it with an opaque cap).
• Druk die NUL button. The display should read "0.00".
• This calibrates the meter to account for any residual sensor output in darkness.

5.9 Unit Conversion (Fc/Lux)

The meter can display measurements in Lux or Foot-Candles (Fc).

• Druk die EENHEID button to toggle between Lux and Fc units.
• The selected unit will be indicated on the LCD.
• Omskakeling: 1 Fc = 10.764 Lux; 1 Lux = 0.09290 Fc.

5.10 Touch Tone and Mute Function

The meter may emit a touch tone when buttons are pressed. This can be muted.

• Refer to the specific button on your device for muting the touch tone.

6. Onderhoud

6.1 Skoonmaak

• Vee die meter se c afasing met 'n sagte, damp lap. Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
